A water recycle system may be implemented to analyze and selectively recycle wastewater generated by an industrial textile washer. In some examples, wastewater generated by the industrial textile washer undergoes various treatment processes, such as chemical treatments (e.g., addition of flocculants, chelating agents) and/or physical separation treatments (e.g., processing in a dissolved air floatation system to remove particulates). This can generate a clarified wastewater. One or more sensors can be positioned to measure characteristics of the clarified wastewater, such as the color of the clarified wastewater and corresponding tendency to stain textile articles if recycled to the washer. Based on measurements from the one or more sensors, the clarified wastewater can be recycled for reuse in the textile washer or, alternatively, discarded.

An indirect evaporative cooling system for cooling a space adjacent to or containing an ablution bay is described. The indirect evaporative cooling system includes a greywater source from the ablution bay and evaporative cooler apparatus located above the space to be cooled in a dome shaped housing. The evaporative cooler apparatus includes a wet channel, at least one spray nozzle, and a dry channel. The at least one spray nozzle is located at the top of the evaporative cooler apparatus and is fluidly connected to the greywater source and the wet channel. The wet channel is located directly above the dry channel. A first side of the dry channel is connected to a first opening with a fan and outside air.

Provided is an antimicrobial glass which can be accommodated in a narrow accommodation space of an antimicrobial water unit for supplying antimicrobial water to a washing tub of a washing machine, and also can effectively suppress an occurrence of black mold or the like in a washing tub and can effectively protect a subject for washing against microbes while suppressing the coloration of the subject.

As an antimicrobial glass for exhibiting an antimicrobial effect by releasing silver ions when brought into direct contact with water, when the total amount is 100% by weight, the content of Ag.sub.2O has a value within the range of above 5% by weight but less than 10% by weight, the content of P.sub.2O.sub.5 and CaO has a value within a predetermined range, the content of ZnO has a value of below 10% by weight, the content of K.sub.2O, Al.sub.2O.sub.3, and MgO has a value within a predetermined range, and the antimicrobial glass has a tablet shape with a maximum diameter value in a predetermined range.

An improved gray water reclamation system. A filter-valve is coupled to a gray water conduit between a drain where gray water enters the system and a gray water tank and/or sump. Water which enters the filter-valve contacts a filter screen which separates the incoming water into a portion of screened water and a portion of particulate matter which remains behind in the main portion of the filter-valve. The portion of screened water continues out of the filter-valve and into the gray water tank. The filter-valve is cleaned or maintained by backwashing the collected contaminates and particulate matter through the normal sewer drain system by opening an installed motor operated valve and allowing the collected particulate matter and backwash to pass there through via the waste conduit. The backwash and particulate matter from the filter-valve is then directed into a second waste conduit which is coupled to a pre-existing drainage system.

A pump device for a water-conducting domestic appliance, such as a washing machine or a dishwasher, has a pump chamber with at least two inlets, and has multiple actuators on or in the pump chamber for a liquid-pumping operation in at least one direction. At least one sensor is provided on or in the pump chamber for determining constituents and properties of the liquid in the pump chamber. A storage chamber is connected to an inlet of the pump chamber and contains additives or analytes for the liquid.

A control method of the washing machine with the washing water recycling function, the method comprises the following steps: Step 1, after the washing stage of the washing machine, feeding washing water into the flocculation barrel, step 2, stirring, flocculating and standing for layering in the flocculation barrel, step 3, refluxing flocculated clean recycling water into the washing barrel, discharging sewage with residual floc, step 4, feeding the tap water into the washing barrel till reaching the rinsing water level, step 5, performing rinsing. In the step 4, before feeding tap water into the washing barrel, it is determined whether or not the washing water inside the washing barrel reaches the rinsing water level L.sub.4. If yes, executing step 5. If no, executing step 4 until the rinsing water level L.sub.4 is reached.

Filtration systems and methods for removing a filter residue from a filter employed in filtering a liquid (for example, grey water). The filtration system may include a vessel having an inlet through which a liquid can be introduced during use and an outlet through which filtered clean liquid can exit. A filter configured to filter the liquid is disposed within the vessel between the inlet and the outlet. The filtration system may further include at least one transducer disposed on or adjacent to the filter. The at least one transducer may be configured to generate one or more pressure waves effective to dislodge at least some residue materials collected on an upstream side of the filter.
